Question

Find the equation of a line that contains the points (−3,−1) and (−4,−7). Write the equation in slope-intercept form

Answer 1

y = -8x -25

Explanation:

The 2-point form of the equation of a line is useful when you are given 2 points.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (7 -(-1))/(-4 -(-3))(x -(-3)) +(-1)

y = 8/-1(x +3) -1

y = -8x -25
